D • (-4) = 32 solve for d

RSB [31]

Answer:

d = -8

Step-by-step explanation:

Isolate the variable, d. Note the equal sign, what you do to one side, you do to the other. Divide -4 from both sides of the equation:

$d * -4 = 32\\\frac{d * -4}{-4} = \frac{32}{-4}\\d = \frac{32}{-4}\\d = -8$

d = -8 is your answer.

Hello :
<span>the parabola's equation is : f(x) = a(x+3)²-1
</span><span>the coefficient of the squared expression in the parabola's equation is : a
but ; f(4) = 0
0 = a(4+3)²-1
